、Reballing Process
1. Fixed the BGA chip which need to be reballed on the under plate of the
adjustable reballing kit, and then adjust the No-spring slider to fix the
chip.
2. Choose the stencil according to the style of chip, then fix the stencil on
the top cover of the adjustable reballing kit and lock the four M3 screws,
cover the cap. Adjust the four screws of the under plate to fit for the height of the chip.
3. Check the alignment of the hole of the stencil and the welding spot of the
chip, if it is in misalignment, then remove the cover and adjust the fixed
slider until it is in alignment.
4.- Lock the fixed slider of the two no-spring slider, take out the BGA chip and wipe a layer of solder
- 14
paste, fixed the chip on the adjustable reballing kit again, cover the cap.
5. Put some solder balls into the kit, clutch and shake it to make all the balls
stand on the welding spot, and at the same time, clear the superabundant
balls.
6. Put the reballing kit on the desk, take out the top cover, and bring out the BGA cheap carefully, and
check it whether there are some balls on the wrong place or not, if it is, then make it right with
tweezers.
7. The way of making the balls fixed is using the Reballing machine, It
can heat the cheap medially. Up to now, we finished reballing.

、 Safety Precautions
！The power supply of W DS -4 2 0 is AC230V, the temperature can arrive to 400℃. If
you do not operate inappropriately, it will cause damaging to the machine or even to
the operator. So you must strictly abide by the following matters:
1. Don't blow to the rework station directly when it is working, or there will be a negative
difference from the surface of the heating board, thus some parts will be burnt out.
2. After it is started, the high temperature area should not touch any objects, or it will lead to a
fire or explosion. The PCB and other parts should be put on the PCB bracket.
3. No vibration. Handle it gently.
- 17 -
4. Don't touch the heaters with your hands when it is working, or you will get hurt.
5. Don't use combustible spray, liquefied and flammable gas near the rework station after it is
started.
6. Don't try to re-equip the machine, or there may be a fire or an electric shock.
7. There are high-pressure parts in the circuit box. Don't disassemble it.
8. If some metals fall in the rework station when it is working, turn off the power immediately.
After it is cooled down, get the metal out, and clean the machine. If not, there may a smell
when the machine starts working next time.
9. When the rework station's temperature rises abnormally or smokes, turn off the power and
inform the service technicians to repair it. Turn off the power of the circuit box and the
machine while moving the rework station. Hold the plug when we remove the wire or it will
lead to a poor contact then the machine can't work very well.
10. Turn off the power when stop using it.
11. Don't put the rework station on the wires, or there may be a failure, a fire, or an
electric shock.
12. Before you use the machine, you must read the instructions attentively.
Note: when the machine works, it will produce some smell. So ensure the comfortable,
healthy and safe operation environment, please keep the air in circulation.
Under the following case, if it causes any damage, it will not in our
guarantee;
1）Do not operate according to the condition of the environment and methods of operation
that the manual book required;
2）The reason out of our product;
3）Not the transformation and maintenance of our company;
4）Do not operate accordance with the way of use that our company's products required;
5）The case that the temporal level of scientific and technological of our company was
impossible to predict;
6）Natural disasters or man-made destruction and such non-responsibility of the Company
premises, it will not in guarantee.
